Personally I've had little issue with most of the points brought up here. LO seems to have gotten a grasp on a real direction for APB's future with the 64 bit work, and has stopped chasing the engine upgrade dragon. The effort spent on implementing and validating work for the current LIVE game is better spent elsewhere; weapon and car balance are largely fine and the outliers that do exist are not game breaking.
Beyond all of that, the misplaced desire to revive the player-base before any meaningful delivery from LO will likely just leave a bad taste in the mouths of those players; "Oh, is the engine upgrade done?" "Oh, is there anything new to do?" Any serious drive to bring back players needs to happen when there's something they can come back to. This game doesn't even run reliably on RTX cards, so many of us can't even play it even if we wanted to.
